ANSON HATCH, OF NEW HAVEN, CONNECTICUT, ASSIGNOR OF ONE-HALF TO AUGUSTUS E. SCHMIDT, OF SAME PLACE.

LUBRICAT ING VERTICAL BEARINGS.

SPECIFICATION forming part of Letters Patent- No. 280,742, dated July 3, 1883.

Application filed May 212, 1883. (No model.) 1

To all whom it may concern:

Be it known that I, ANsoN HATCH, of New Haven, in the county of New Haven and State of Connecticut, have invented anew Improvespindles which stand in a vertical position.

In this class of bearings the oil, as usually applied, unless there be so much applied as will run to waste, fails to enter the bearing to give the proper lubrication, and naturally the oil works out around the shoulder of the spindle and runs down upon the outside of the bearing or box, not only wasting the oil, but soiling the machinery.

The object of my invention is to provide a device whereby a supply of oil will be retained at the shoulder and its entrance to the bearing insured and it consists in a cup-shaped collar arranged between the shoulder of the spindle and the upper side of the bearing, the body of the spindle standing in the cup, and as more fully hereinafter described.

A represents one bearing for a vertical spindle, B. Between the top of the bearing and the shoulder of the spindle I introduce a cupshaped ring, 0. (This ring shown detached in Fig. 3.) The opening through the ring corresponds to the diameter of the bearing.

The flange a, which forms the side or wall of the cup, is a little larger in its internal diameter than the diameter of the spindle, and so that the body of the spindle will pass down 5 into the cup and rest 011 the ring, the ring or horizontal part of the ring lying between the shoulder and the top of the bearing, as seen in Fig. 2. Oil is introduced within the flange a, and, in the revolution of the spindle, works its way beneath the shoulder and is conducted down into the bearing.

The collar is independent of both the spindle and bearing, so that it may revolve with the spindle or rest upon the bearing, as the case may be. In practice this loose arrange ment of the collar sometimes rotates and some times rests. This intermittent rotary movement of the collar aids in the proper distribution of the oil.

A surplus of oil may always be present within the flange without liability of running to waste, because the collar rests so closely upon the top of the bearing and there is so little rotation of the collar that the oil is not 6 5 liable to work out between the collar and the top of the bearing.

I claim The combination of a vertically-revolving spindle, the bearing which supports it, and a 70 cup-shaped ring between the shoulder of the spindle and the top of the bearing, and unattached to either the spindle or bearing, the in ternal diameter of the cup larger than the diameter of the body of the spindle, substantially as described.

ANSON HATCH.
